New paper -- GMAW-P Welding of Copper-nickel Pipe Joints for Shipbuilding Applications

Virtually all ship designs utilize copper-nickel alloys for applications such as fire mains and other seawater/freshwater piping, tanks, and structures such as rope guards and fairings. The manual gas tungsten arc welding (GTAW) process that is typically used to weld copper-nickel pipe joints has relatively low productivity due to slow travel speeds and low deposition...

New Paper – Joining Challenges in the Manufacture of Motors for Electric Vehicles – Stator Winding Assemblies

Stator windings in traction motors for electric vehicles are created by joining multiple short copper wire sections. Current joining approaches for these multiple copper wire sections lack the productivity for high volume manufacturing, require an increased amount of copper for assembly, and risk reduced joint strength due to softened copper from extended thermal cycles. In...

EWI Research Helps MTI Develop Low-force Friction Welding Solution for Rail

The rail industry has long been seeking a more dependable, longer-lasting way to weld rail lines. The standard joining methods, flash-butt welding and thermite welding, produce joints with short weld lives and require frequent repair. To address this issue, EWI conducted research on linear friction welding (LFW) as a potential method for joining rail. The...
